I am using 6403D and trying to do programming with SDK.Please comment on the following issues at the original function form of an Labview example, "uint32_t _ps6000OpenUnit@8(int16_t *handle, CStr serial)."

1. Why do you use "_ps6000OpenUnit" instead of "ps6000OpenUnit"? It is slightly different from your Programmer's Guide. 2. What do they mean @8 ?
